Thanks Jeff. That was my initial plan. Then a friend & I stared thinking about constant vacuum being applied to the fuel tank. As it has no other venting, I am fearful that could easily stall the car, or maybe even collapse the fuel tank. That negative pressure can be a powerful force.
AFAIK, the systems in our modern cars have a control valve to purge the charcoal canister at start up, then eliminate the vacuum during driving.

Anybody else have such a system?
